Blue light st supercharger

I have a 2015 model s. Over the last week, I have had major problems at superchargers. I keep getting a flashing and then solid blue light, over and over again. The screen in the car either says, “starting to charge” or “charging stopped”. I’ve tried multiple stalls over about a week in Oregon and Washington, both v.2 and the metro super chargers. Sometimes I can eventually get it to go green, other times it never works.

My car charges great at home. And, I have a chademo adapter which still works every time on Blink.

I called the number on the supercharger, and the nice Tesla rep had me perform a hard restart via the touchscreen (safety & security > Power off) and wait about a minute. My car then charged on the first attempt. However, after charging for about 30 mins, I unplugged the supercharger and waited about a minute ad tried again at the same stall. No luck. I couldn’t get it to charge for anything. Lots of blue and blue flashing, even after two more hard restarts, and eventually I gave up and left.

I find it strange that I can charge at home with 40 amps and at the high speed blink charger with chademo at about 45 kw, but I have all sorts of issues at superchargers.

Any ideas on what’s wrong?

Thanks in advance.
 
I had the same exact thing on my 2015 Model S. It was a bad onboard charger. Yes, it seems counter-intuitive that a bad charger would charge at home but not supercharge, but that was it. Because the supercharger bypasses the onboard charger and puts DC straight into the battery, I initially thought it was a problem with the widget that bypasses the onboard charger (I think it's called the DC-to-DC converter) but, no, it was the charger itself. $2000 at my local SC. It's not included in the battery/drivetrain warranty.
